A: Railway manufacturers, operators, and regulatory bodies should use ISO 5948:2018 to ensure compliance with international standards.
The standard now includes more stringent criteria for components destined for high-speed rail or high-axle-load applications. 3. Core Testing Requirements
To ensure maximum coverage, the standard limits "dead zones" (areas where defects might be missed). Typical limits are 30 mm generally, but reduced to 10 mm for wheel treads and 15 mm for hollow-axle bores.
Added techniques to determine how well ultrasound travels through specific axle materials. High-Speed Requirements:
